Not 100% tested. CB = total capacitance of one bus line in pF.
As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved
noise spike suppression. This eliminates the need for a TI specification for standard operation.
This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ Model which can be obtained at www.microchip.com.

SDA Serial Data
This is a bidirectional pin used to transfer addresses
and data into and data out of the device. It is an open
drain terminal, therefore the SDA bus requires a pull-up
resistor to VCC (typical 10 k for 100 kHz, 2 k for
400 kHz).
For normal data transfer SDA is allowed to change only
during SCL low. Changes during SCL high are
reserved for indicating the Start and Stop conditions.
2.2
SCL Serial Clock
This input is used to synchronize the data transfer from
and to the device.
2.3
Noise Protection
The SCL and SDA inputs have Schmitt Trigger and
filter circuits which suppress noise spikes to assure
proper device operation even on a noisy bus.

FUNCTIONAL DESCRIPTION
The 24XX00 supports a bidirectional 2-wire bus and
data transmission protocol. A device that sends data
onto the bus is defined as a transmitter, and a device
receiving data as a receiver. The bus has to be
controlled by a master device which generates the
Serial Clock (SCL), controls the bus access, and
generates the Start and Stop conditions, while the
24XX00 works as slave. Both master and slave can
operate as transmitter or receiver, but the master
device determines which mode is activated.
4.0
BUS CHARACTERISTICS
The following bus protocol has been defined:
• Data transfer may be initiated only when the bus
is not busy.
• During data transfer, the data line must remain
stable whenever the clock line is high. Changes in
the data line while the clock line is high will be
interpreted as a Start or Stop condition.
Accordingly, the following bus conditions have been
defined (Figure 4-1).
4.1
Bus Not Busy (A)
Both data and clock lines remain high.
4.2
Start Data Transfer (B)
A high-to-low transition of the SDA line while the clock
(SCL) is high determines a Start condition. All
commands must be preceded by a Start condition.
4.3
Stop Data Transfer (C)
A low-to-high transition of the SDA line while the clock
(SCL) is high determines a Stop condition. All
operations must be ended with a Stop condition.
4.4
Data Valid (D)
The state of the data line represents valid data when,
after a Start condition, the data line is stable for the
duration of the high period of the clock signal.
The data on the line must be changed during the low
period of the clock signal. There is one bit of data per
clock pulse.
Each data transfer is initiated with a Start condition and
terminated with a Stop condition. The number of the
data bytes transferred between the Start and Stop
conditions is determined by the master device and is
theoretically unlimited.

Acknowledge
The device that acknowledges has to pull down the
SDA line during the Acknowledge clock pulse in such a
way that the SDA line is stable low during the high
period of the acknowledge related clock pulse. Of
course, setup and hold times must be taken into
account. A master must signal an end of data to the
slave by not generating an Acknowledge bit on the last
byte that has been clocked out of the slave. In this
case, the slave must leave the data line high to enable
the master to generate the Stop condition (Figure 4-2).
Each receiving device, when addressed, is obliged to
generate an acknowledge after the reception of each
byte. The master device must generate an extra clock
pulse which is associated with this Acknowledge bit.
Note:
The 24XX00 does not generate any
Acknowledge bits if an internal programming cycle is in progress.

DEVICE ADDRESSING
After generating a Start condition, the bus master
transmits a control byte consisting of a slave address
and a Read/Write bit that indicates what type of
operation is to be performed. The slave address for the
24XX00 consists of a 4-bit device code ‘1010’ followed
by three “don’t care” bits.
The last bit of the control byte determines the operation
to be performed. When set to a one a read operation is
selected, and when set to a zero a write operation is
selected (Figure 5-1). The 24XX00 monitors the bus for
its corresponding slave address all the time. It
generates an Acknowledge bit if the slave address was
true and it is not in a programming mode.

WRITE OPERATIONS
6.1
Byte Write
condition. This initiates the internal write cycle, and
during this time the 24XX00 will not generate Acknowledge signals (Figure 6-1). After a byte Write command,
the internal address counter will not be incremented
and will point to the same address location that was just
written. If a Stop bit is transmitted to the device at any
point in the Write command sequence before the entire
sequence is complete, then the command will abort
and no data will be written. If more than 8 data bits are
transmitted before the Stop bit is sent, then the device
will clear the previously loaded byte and begin loading
the data buffer again. If more than one data byte is
transmitted to the device and a Stop bit is sent before a
full eight data bits have been transmitted, then the
Write command will abort and no data will be written.
The 24XX00 employs a VCC threshold detector circuit
which disables the internal erase/write logic if the VCC
is below 1.5V (24AA00 and 24LC00) or 3.8V (24C00)
at nominal conditions.
Following the Start signal from the master, the device
code (4 bits), the “don’t care” bits (3 bits), and the R/W
bit (which is a logic low) are placed onto the bus by the
master transmitter. This indicates to the addressed
slave receiver that a byte with a word address will
follow after it has generated an Acknowledge bit during
the ninth clock cycle. Therefore, the next byte transmitted by the master is the word address and will be
written into the Address Pointer of the 24XX00. Only
the lower four address bits are used by the device, and
the upper four bits are “don’t cares.” The 24XX00 will
acknowledge the address byte and the master device
will then transmit the data word to be written into the
addressed memory location. The 24XX00 acknowledges again and the master generates a Stop

ACKNOWLEDGE POLLING
Since the device will not acknowledge during a write
cycle, this can be used to determine when the cycle is
complete (this feature can be used to maximize bus
throughput). Once the Stop condition for a Write
command has been issued from the master, the device
initiates the internally timed write cycle. ACK polling
can be initiated immediately. This involves the master
sending a Start condition followed by the control byte
for a Write command (R/W = 0). If the device is still
busy with the write cycle, then no ACK will be returned.
If no ACK is returned, then the Start bit and control byte
must be re-sent. If the cycle is complete, then the
device will return the ACK and the master can then
proceed with the next Read or Write command. See
Figure 7-1 for flow diagram.

8.0
READ OPERATIONS
Read operations are initiated in the same way as write
operations with the exception that the R/W bit of the
slave address is set to one. There are three basic types
of read operations: current address read, random read
and sequential read.
8.1
Current Address Read
The 24XX00 contains an address counter that maintains the address of the last word accessed, internally
incremented by one. Therefore, if the previous read
access was to address n, the next current address read
operation would access data from address n + 1. Upon
receipt of the slave address with the R/W bit set to one,
the device issues an acknowledge and transmits the
eight-bit data word. The master will not acknowledge
the transfer, but does generate a Stop condition and the
device discontinues transmission (Figure 8-1).
8.2
Random Read
Random read operations allow the master to access
any memory location in a random manner. To perform
this type of read operation, first the word address must
be set. This is done by sending the word address to the
device as part of a write operation.
FIGURE 8-1:
8.3
Sequential Read
Sequential reads are initiated in the same way as a
random read except that after the device transmits the
first data byte, the master issues an acknowledge as
opposed to a Stop condition in a random read. This
directs the device to transmit the next sequentially
addressed 8-bit word (Figure 8-3).
To provide sequential reads the 24XX00 contains an
internal Address Pointer which is incremented by one
at the completion of each read operation. This Address
Pointer allows the entire memory contents to be serially
read during one operation.

After the word address is sent, the master generates a
Start condition following the acknowledge. This terminates the write operation, but not before the internal
Address Pointer is set. Then the master issues the
control byte again, but with the R/W bit set to a one.
The 24XX00 will then issue an acknowledge and transmits the eight bit data word. The master will not
acknowledge the transfer, but does generate a Stop
condition and the device discontinues transmission
(Figure 8-2). After this command, the internal address
counter will point to the address location following the
one that was just read.

Year code (last digit of calendar year)
Year code (last 2 digits of calendar year)
Week code (week of January 1 is week ‘01’)
Alphanumeric traceability code (2 characters for small packages)
Pb-free JEDEC designator for Matte Tin (Sn)
For very small packages with no room for the Pb-free JEDEC designator
e3 , the marking will only appear on the outer carton or reel label.
In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line, thus limiting the number of available
characters for customer-specific information.
Please visit www.microchip.com/Pbfree for the latest information on Pb-free conversion.
*Standard OTP marking consists of Microchip part number, year code, week code, and traceability code.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
